H. w. FISHER LFLUID' DISPENSING DEVICE Filed May 5, 1933 ATTORNEYSPatented @ct. 10, 1933 UNITED STATES PATENT OFFICE l- 8 Claims.

The present invention relates to a fluid dispensing device which isparticularly useful in handling a cleansing fluid such as gasoline.

The primary object of the invention is to provide a fluid dispensingdevice, specifically a bottle with a closure member or cap therefor, bymeans of which a cleansing operation can be performed without removingthe cap simply by turning it slightly to permit egress of fluid upon 19inversion of the bottle and then rubbing the spot to be cleaned with apad of felt or other similar material affixed to the top of the closuremember.

A more detailed recitation of the objects of 1 my invention includes (1)the provision of a bottle having a cap which can be rdtatedin onedirection to seal the bottle against egress of fluid and in the otherdirection to permit discharge of a limited quantity of the fluid which90 is just suflicient for convenient application in a cleansingoperation; (2) the provision of a device of the character described inwhich adequate distribution of the fluid over the area of the cleaningpad may be effected; (3) the pro- 5 vision of a cleaning bottle of thecharacter mentioned in which 'the cap or closure member is non-removableso that the bottle cannot be refilled without distorting or impairingthe usefulness of the cap; (4) the provision of a device of thischaracter which is of simple yet sturdy construction, easy tomanufacture, and reasonable in cost.

The nature of the invention and its objects will be more clearlyapparent and better understood in connection with the followingdescrip-- tion of the accompanying drawing, wherein- Fig. l is avertical section through the upper portion of a bottle equipped with myimprovements showing the cap in the position which it assumes when thebottle is tightly closed.

Fig. 2 is a side elevation of the upper portion of my improved devicetaken in a direction at right angles to the section of Figure 1, butwith the outer protecting cover removed.

Fig. 3 is a side elevation of the neck portion of my improved bottletaken at right angles to the elevation shown in Fig. 2 and with aportion of the neck broken away to illustrate certain features of theconstruction in section.

Fig. 4 is a plan view of the neck of the bottle. Fig. 5 is a section ofthe neck of the bottie with the cap in place showing the position whichthe latter occupies during a cleansing 0peration.

In connection with Figs. 1 and 5, I should like to point out that thesections illustrated in these figures are taken approximately asindicated by the section line with the arrows appearing in Fig.4,-although it will be understood, of course, that the cap in Fig. 1occupies a different circumferential position than it does in Fig. 5.

Referring to the drawing it will be seen that the neck portion 8 of thebottle 9 is provided across its top with a substantially flat webportion 10 in which is formed the eccentrically disposed aperture 11through which the cleaning fluid can be discharged when the cap is inposition to permit such discharge, as will appear hereinafter.

At its upper margin the neck is provided with a shoulder or head 12which is cut away at two diametrically opposite points to provide thechannels or grooves 13.-

Just below the shoulder 12 there is formed on the neck a pair ofoppositely disposed sections of a right hand cam 14 and a similar pairof op- 'positely disposed sections of a left hand cam 15.

Adjacent sections 14 and 15 meet in a stopsshoulder 16 and extendsubstantially half-way around the neck of the bottle so that eachsection 14 occupies roughly only one-quarter of a circumference and eachsection 15 another quarter of the circumference. However, there are tworight hand sections 14 located at diametrically opposite points, as wellas two left hand sections 15 also diametrically disposed to occupysubstantially the other two quarters of the circumference. Adjacentsections 14 and 15 terminate at points substantially 180 apart so as toprovide the vertical channel or groove 13a. at each side of the bottle,which channels are, in effect, continuations of the channels 13formed-in the bead or shoulder 12. The effect of the arrangement is toprovide the bottle neck with what may be termed a half-right-half lefthand cam surface.

The closure member or cap used in connection with my improved dispensingdevice includes a cup-shaped sealing member 17, the side wall or skirt18 of which fits down around the top of the neck of the bottle in orderto embrace the shoulder 12 and the cams 14 and 15.

At two diametrically opposite points the skirt 18 is provided with theindents 19 which, when the cap is placed in position, are adapted to fitinto the slide through the vertical grooves or channels 13, 13a. Uponsubsequent rotation of the cap it will be clearly understood that theindents 19 will engage beneath the cams 14 when the cap is turned in onedirection and beneath the cams 15 when the cap is turned in the oppositedirection. In either direction, however, it is obvious that the cap willbe tightly held against the top of the bottle in order to preventleakage.

Interiorly the cap is provided with any suitable type of washer orgasket member 20, preferably of cork.

Eccentrically disposed but located on the diameter which passes throughthe two indents 19 the cup-shaped cap 1'7 is provided with a relativelyrestricted discharge orifice or outlet 21, and the gasket member 20 isprovided with a suitable aperture 22 adapted to register therewith, al-

though the aperture 22 may be of larger diameter if desired. In fact Iprefer to make the aperture 22 of a diameter substantially correspondingto the diameter of the discharge opening 11 in the web 10 of the bottleneck. The gasket member 20 may be held in place in any suitable ordesired manner.

The cap member is also provided with a domeshaped supporting plate 23having a plurality of perforations 24, which plates serves as a backingmember for the cleaning pad 25. The pad may be made of felt or any otherporous and absorbent material suitable to the purpose.

The lower edge of the plate 23 is bent outwardly and upwardly around theedge of the felt 25, as indicated at 26, and by crimping in theoutermost edge slightly as shown at, 27, the cleaning pad can be veryeffectively held in position. The construction of the plate 23 is suchas to provide a relatively large distributing chamber 28 between theflat top of the cap 17 and-the pad 25 which serves to distribute thecleaning fluid, as will appear below in connection with a description ofthe manner in which the device is used. The cap 17 and the backing plate23 may be secured together in any desired manner, as by welding shown at29.

The lower portion of the neck of the bottle is provided with the threads30 over which is screwed the cover member 31, the latter serving as ameans for keeping the device in clean con-. dition when not in use.

After the bottle is filled with the cleaning fluid the cleaning cap orclosure member is placed in position with the indents 19 fitting intothe vertical recesses or grooves 13, 13a. Then, by rotating the cap inthe direction of the arrow 32 in Fig. 6, the opening 22 in the corkgasket 20 will be brought to the dot and dash position shown at 22c. Inthis position the indents 19 have passed under the right hand cams 14which serve to hold the cap in tight position against the top of thebottle so as to seal the opening 11. By turning the cap 19 in thedirection of the arrow 33 in Fig. 6 the opening 2 2 can be brought tothe dot and dash position 22b where it will register with the opening 11in the web 10 of the bottle. During this motion the indents 19 engagethe under surface of the left hand cams 15,

' and when the openings 22 and 11 are in registry the gasket 20 istightly pressed against the top of the bottle in order to preventleakage laterally between the cap and the top web of the bottle, egressof fluid during a cleaning operation, taking place, of course, throughthe openings 11, 22 and 21.

When the bottle is inverted for a cleaning operation the fluid entersthe distributing chamber 28 from which it passes through theperforations 24 into the cleaning pad 25. A gentle rubbing motion willserve to scatter the cleansing fluid as it enters the chamber 28 so thatit will be substantially uniformly distributed throughout the cleaningpad.

Fig. 2 shows the cap withthe indents 19 in the vertical channels 13,13a, and in this position the side wall or skirt 18 of the cap may becrimped in at the sides intermediate the indents 19 as indicated at 34.The crimped portions 34 will extend beneath the shoulder 12. It will beseen, therefore, that once the cap has been applied it is non-removableand the bottle is non-refillable unless, of course, the cap is mutilatedand its usefulness impaired.
